Title: Improved method of and apparatus for the purification of water
IPC: C02F1/76
Filed: 1951-06-27
Abstract: 733,915. Purifying water; filters. SMALLEY, W., and O'DONOVAN, R. J. June 19, 1952 [June 27, 1951], No. 15266/51. Class 46. [Also in Group VI] An excess of purifying and/or sterilizing agent is first added to water, and any residual agent is then removed by passing the water through a bed of activated carbon or other adsorbing or dechlorinating material, the lower part of the bed being admixed or contacted with a sterilizing agent such as silver deposited on grit, sand or activated carbon. Water from a tank a passes through a venturi in a pipe f, the throat of the venturi being connected to a suction pipe g immersed in sodium hypochlorite solution in a container b, preferably transparent. The rate of addition of reagent is varied by varying the concentration of reagent or by changing the orifice member g1 for one of a different aperture size, or both. The treated water passes to a trough i, constituting a liquid seal, and thence to a tank k, whence it flows into an inert vessel m containing a bed p of activated carbon or the like where excess reagent is adsorbed. Below the bed p and separated from it by a screen r made from an alloy inert to activated carbon is a mass p1 of silver-coated grit or sand, from which the water is drawn off by a pipe o. In an alternative construction the container for the dechlorinating agent may be constructed of porous or permeable material and immersed in the tank k. Alternatively the super-chlorinated water may be drawn off from the tank k (which may or may not be provided with a filter for the clarification of the water prior to or after de-chlorination) through a bed of dechlorinating material in the base of the tank. An air-vent tube h, the lower end of which is at a slightly higher level than the lower end of the suction tube g, may be provided in the reagent container b.

Title: Improvements in or relating to the photoelectric inspection of sheet materials
IPC: B07C5/342
Filed: 1969-03-24
Abstract: 1,217,642. Photo-electric inspection. OMRON TATEISI ELECTRONICS CO. March 24, 1969 [April 8, 1968j, No.15268/69. Heading G1A. A moving web is inspected photo-electrically for faults which involve defective parts standing out from its surface by a narrow beam of light close to the surface and directed across the web at right angles to the direction of movement, total or partial reflection of the beam by a defect being detected by a lateral array of photo-cells. The beam which may be a laser beam may cross the web in the vicinity of a roller, and may be chopped to facilitate amplification and two close parallel beams may be directed one from each other. The apparatus may include additional fault detecting apparatus for holes or marks, the light beam of which may shine through the web and the detector of which may respond to its absorption or reflection. In a circuit for the point control of a fault marking system including the detectors of two lateral arrays, outputs of corresponding detectors are applied after pre-amplifications to provide with the output of another pair the input to a differential amplifier the output from which is used to effect control or marking error a threshold circuit.

Title: Switching network for coded messages
IPC: H04Q11/04
Filed: 1975-04-15
Abstract: 1483273 Automatic exchange systems INTERNATIONAL STANDARD ELECTRIC CORP 15 April 1975 [18 April 1974] 15411/75 Heading H4K A space switching stage for use in a TDM switching system is divided into a plurality of independently controlled parallel planes and a distribution circuit is provided for distributing coded messages received in parallel format to said planes in serial format or in a hybrid combination of a serial and parallel format. The space stage forms part of a T-S-T network wherein PCM words received in serial form on an incoming highway E2 are fed into storage locations in a time stage store ME2 in parallel format. The words are read out in parallel form to the distributer DE2 which converts the parallel words back to serial form and distributes the words to the four plane space network P1-P4 such that the planes are sequentially used. A further unit DS3 converts the serial words back to parallel form and supplies them to the outgoing time stage MS3. The arrangement is said to overcome the problems that occur when the space switching takes place in parallel bit fashion and one of the planes becomes faulty thereby deleting a bit from every PCM word. In the above arrangement a fault on one plane leaves 75% of the traffic unaffected. However, a spare space switching plane may be provided to take over under fault conditions. Several variations on the Fig. 1 arrangement are disclosed. In a first the parallel to series conversion takes place in two stages (Fig. 5, not shown). A first unit equivalent to DE2 converts the parallel words into two four bit words which are supplied in parallel to a unit situated physically adjacent the space switch plane, which unit combines the two parallel four bit words to an 8 bit serial word for the space switching. An alternative variation is to combine the planes into groups and to transmit a word in semi-parallel form via the planes of one group, e.g. if each group comprised two planes, a word would be switched as two parallel groups of four serial bits.

Title: Improvements in or relating to power assisted systems for controlling a movable body subject to external forces
IPC: G05D1/00
Filed: 1941-12-10
Abstract: 612,810. Fluid-pressure servo motor-control systems. HILLIER, A. (Sperry Gyroscope Co., Inc.). Dec. 10, 1941, No. 15821/44. Divided out of 612,804. [Class 135] [Also in Groups XXXIII and XXXVIII] In a control system the force applied to a controlled member such as an aircraft control surface, is made proportional to the force applied to a control. member by coupling the control member to a constrained member through an elastic coupling and providing a pick-off which applies signals to a servomotor mechanism actuating the control member, in proportion to the relative movement of the control member and the constrained member. As shown in Fig. 1, control member 57 is elastically coupled to column 58 and a pick-off is associated with the two members (see below) which gives A.C. signals proportional in magnitude and phase to the direction and magnitude of the lateral force applied to member 57, these are applied to amplifier-demodulator 19 which introduces a rate of charge component (see below). Referring also to Fig. 6, the amplifier output. consisting of two D.C. voltages varying in relative magnitude is applied to torque motor coils 21 and 21<1> so that control member 23 of balanced oil valve 25 is subjected to a force proportional to that on member 57. The effect of this, as described in Specification 538,526 is that servomotor 26 exerts a force, proportional to that on member 57, on control surface 27. Member 58 is coupled to control surface 27 so that direct control may be effected in the event of power failure. Fig. 2 shows the mounting of wheel 57 which is coupled to shaft 62 which is in turn coupled by elastic coupling 64 to outer member 63 which is free to rotate in column 58. Axial movement of shaft 62 causes armature 68 to differentially vary the coupling between the centre energized coil and the series opposition connected outer coils mounted on yoke 67, as is shown by the plan view of Fig. 4 and the axial view of Fig. 3, a further pair of series opposition connected coils is provided to co-operate with armature 63 and the central energized core to provide signals for similarly actuating another control surface in response to any turning of wheel 57 relative to outer member 63, which may be similarly coupled to the control surface by wire 60. Fig. 5 shows the circuit of unit 19 which comprises two pairs of balanced demodulator valves 38, 381 and 40, 401, the output of the former being applied to the input of the latter through differentiating networks 42, 43 and 421, 431 so that the output of the valves 40, 40<1>, which is applied to amplifier stages 44, 44', contains a rate of change component.

Title: Improvements in and connected with respiratory apparatus
IPC: A61M16/00
Filed: 1949-06-14
Abstract: 672,219. Respiratory appliances. WOOD, C. R. March 13, 1950 [June 14, 1949], No. 15856/49. Class 81 (ii). A respiratory apparatus comprises a source of gas under pressure and a valve, actuated by an electric motor, which connects the lungs alternately to the source of gas and to atmosphere. The appliance is intended primarily for use with animals and in its preferred form provides two cylinders 1, 2, Fig. 1, containing compressed oxygen and air respectively, through flow meters 5, 6 to a common pipe 7. A liquid anµsthetic container 9 may be optionally connected into the oxygen supply by means of a by-pass turn-cock 10. The pipe 7 leads to the motor-driven valve arrangement 8 and this is connected to a tube 11 which is retained in the animal's trachea by inflating a bladder 11a by a bulb 12. The valve is of the two-land piston type and is coupled to a crank disc 20, Fig. 3, driven through reduction gearing by a motor 13, this having a controllable speed. In its extreme right position, as shown, the valve allows direct communication from the inlet port to the pipe 11. From this position it is drawn back past the point where land 24b closes both ports to a point where it is clear of both, so that both are open to atmosphere through vent orifice 25c. When this condition exists, a deflector vane 26, attached to the end of the valve piston, prevents direct communication between the inlet port and tube 11 and deflects gas from both through the outlet 25c. Electrical contacts may be operated by the crank shaft to give an indication of the condition of the valve.

Abstract: 1,099,118. Programmed control of fountains. K. KAWAMURA, Y. KAWAMURA and K. KAWAMURA. April 12, 1966, No.15866/66. Heading G3N. [Also in Division F1 A device for recording, modifying and reproducing electrical signals for controlling water fountains, having a plurality of nozzles supplied through valves, employs a shift register to transform sets of simultaneous control signals into a series of sequential control signals which are recorded and vice-versa. As shown, control signals from a generator 36, comprising a keyboard, are sampled by a unit 22 incorporating a plurality of gates which are opened by a signal S from a pulse generator 24 to present the sampled set of control signals to bi-stable units, Fig. 2 (not shown), of a shift register 21. The shift register is shifted by a signal T from a pulse generator 25 to produce a sequential series of control pulses which are amplified by a unit 27 and recorded on a tape 44 by a head 33. At the same time a synchronizing signal C1, which is derived by combining the shift pulse T and a sampling pulse by a pulse generator 26, is amplified by a unit 31 and recorded by the head 33. The programme is reproduced by reading the synchronizing signal by a head 35 and controlling the pulse generators 24, 25 through an amplifier 30. The sequential control pulses are also sensed by the head 35 and through an amplifier 29 are stored in the bi-stable units of the shift register 21 under control of the derived shift pulses T. The register is read by an output sampler 23, comprising a plurality of gates, in response to a derived sampling pulse S'. The sampled control signals are stored in pulse duration modulators 32 for actuating relays 37 controlling hydraulic valves, (not shown), of the fountain. Modification of the recorded control signals is effected by energizing the amplifiers 27, 29 simultaneously and erasing the original control and synchronizing signals by a head 34 the time delay between reproducing, erasing and recording being determined by the physical displacement of the heads. In another embodiment, Fig. 6 (not shown), facilities are provided for recording background music on the tape.
